Question on HSM TSM.
All, In an environment where you are using HSM to manage disks (say for example Windows drives) after a period of time the file will be migrated to a storage pool within TSM and a stub file is left on the filesystem as a marker. I'm assuming that when this migration happens the TSM backup/archive client identifies the change and only backs up the stub - or does it need to recall the file from HSM and then back it up? If it does only backup the stub the issue is that you do not have a copy of a real file only a stub and no data. Can someone give me an idea as to how they have this type of scenario implemented within their environment? kind regards, Rowan.
Re: Question on HSM TSM.
Richard, I agree with what you say, and it is pointless in restoring the file to the original filesystem just to back up that file if it is already migrated to tape. I see that there is an option with DiskXtender to do a backup of the file to TSM before it is migrated to tape and any subsequent backups of the file can be ignored if the file size is zero Still reading ;) kind regards, Rowan O'Donoghue Technical Services Manager Unitech Systems Unit 2, First Floor, Bracken Court, Sandyford Industrial Estate, Dublin 18.

It backs up the file, either from the file system or directly from the HSM storage pool if migrated and using same server. See the (old) HSM redbook at http://www.redbooks.ibm.com/abstracts/sg244631.html which explains how it all works in different configurations, and advises on restoral methods.

IBM 3584 Problems (tapes getting stuck in control path drive) with Solaris
Hi, I noticed a while back that a few people were having problems with the IBM3584's and some flavours of Unix. The problems mainly surrounded the issue of LTO tapes getting stuck in the drive that is also the control path for the library. I'm having the same problem now with both of my Solaris servers and my two 3584 libraries. I have G2 drives at 2CKH firmware and when I perform an audit libr the tape that gets placed into drive 1 (element 257) always gets stuck and never ejects. I've also had scenarios where I have had to get an engineer in to remove the tape manually. I am going via SAN and am sharing the tape drives out to Solaris and Windows systems. Everything seems to be going to plan so far (apart from the performance on the Solaris SAN clients) and LAN-free backups are working perfectly. I have noticed the tapes to get stuck in the same drives when performing a backup stg from one library to another. Anyone ever know what resolved this? I'm beginning to tear my hair out! I've just pulled down the latest IBMtape device drivers for Solaris (v4.0.8.0) but still no joy. Anyone? regards, Rowan O'Donoghue Technical Services Manager Unitech Systems Bracken Business Park Bracken Road Sandyford Industrial Estate Dublin 18.

Shared mem with Solaris LAN-Free
All, I keep getting the error when trying to run the sharedmem commethod on the TSM Storage Agent on my Sun Solaris server. ANR9600E Failed to allocate memory for shared memory communications. Error: EINVAL. ANR8289W Shared Memory driver is terminating due to error in creating a new thread. Anyone got any ideas on how to resolve this?

TSM 5.2 Sun Solaris - Language Format problems.!??!!!
Had TSM 5.1 installed with no problems in this environment before. Using Solaris 8, and TSM 5.2 Upon installing the TSM 5.2 server code I get the following errors: Error opening catalog /opt/tivoli/tsm/server/bin/dsm/en_IE.ISO8859-15/en_IE.ISO8 859-15/en_IE.ISO8859-15/en_IE.ISO8859-15/en_IE.ISO8859-15/C.cat, for language /e n_IE.ISO8859-15/en_IE.ISO8859-15/en_IE.ISO8859-15/en_IE.ISO8859-15/en_IE.ISO8859 -15/C ANR0915E Unable to open language /EN_IE.ISO8859-15/EN_IE.ISO8859-15/EN_IE.ISO8 8859-15/EN_IE.ISO8859-15/EN_IE.ISO8859-15/C for message formatting. I assumed that these would just be warning errors, but after using DSMFMT to format my database and log volumes I cannot use the DSMSERV FORMAT commant as it comes back with a message saying that the format parameters are missing!!!??!!! Anyone else having this problem? I'm using: DSMSERV FORMAT 1 /opt/tivoli/tsm/server/bin/log1.dsm 1 /opt.tivoli/tsm/server/bin/db1.dsm The DSMFMT command was tried first, but no joy. Is the error in relation to the language the one causing the problems? if so, I'm gonna have a problem as the locale on all these servers has to stay EN_IE (Irish). Anyone? Maybe one for the SUN gurus! R.
Two TSM Servers with a Storage Agent?
Hi guys, I want to be able to configure a server using the LAN-free storage agent to be able to back up to storage pools on two different TSM servers. I.e. It will backup direct to tape via the SAN to a backup storage pool defined on one TSM server, and also backup direct to tape via the SAN to an ARCHIVE storage pool define on another TSM server. Can I just define two tsm storageservers on the storage agent??? Anyone know if this is possible? regards, Rowan O'Donoghue Technical Services Manager Unitech Systems Bracken Business Park Bracken Road Sandyford Industrial Estate Dublin 18.

Subfile backups (or Adaptive Copy)
All, Have a customer looking at subfile backups for two webservers which are hosted at a remote hosting facility and connected via a WAN. We are looking at using subfile backups to enable these servers to participate within the TSM hierarchy, but I want to get a feel of real-world-experiences from people who are actually using it in production at the moment. What have been your main issues? (apart from the obvious being expanded TSM processing time on the client, and slow restores). Also, how have you sized the subfile cache area? Was there a rule of thumb for this sizing? thanks! Rowan.
Re: AW: Subfile backups (or Adaptive Copy)
Interesting to note about the transfer of the full file after the 32 subfile backups - does this definitely happen? You mention that 1GB was used as the subfile cache area...how big was the amount of space available on the server? I believe that the TSM client does not perform housekeeping on this directory (i.e. it does not clean out old binary images) and you have to do this yourself. thanks, Rowan.

I ended in purchasing extra bandwidth and performing regular forever incremental. I still have got a very small client location where subfile backup simply works and works - no troubles at all so far. Another point to watch is that regulary, I believe after each 32 subsequent subfile backups, full file size will be transfered once again. regards juraj salak -Ursprüngliche Nachricht- Von: Rowan O'Donoghue [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 14.

TSM DR
All, The one thing I've always found to be a downside to TSM is the ability to easily identify the EXACT amount of tapes required to rebuild an environment to it's most current state. I have wrote SQL scripts previously which performs a query against each TSM client and it's filespaces for those files marked as ACTIVE and then linked to the tape which held these files. select distinct(con.volume_name) from contents con,backups bak where concat(concat(bak.hl_name,' '), bak.ll_name)=con.file_name and bak.state='ACTIVE_VERSION' and con.node_name='STEGANOS' and con.type='Bkup' The trouble with this query/script is that it took forever for it to run and would not be much use during a DR scenario. Is there a simpler way to do this? Again, rather than recall all offsite pool tapes, I only want the bare minimum to recover the systems to their most recent state. regards, Rowan O'Donoghue Technical Services Manager Unitech Systems Bracken Business Park Bracken Road Sandyford Industrial Estate Dublin 18.

Re: TSM DR
Agreed, it is probably the most important shortcoming! In terms of when a DR is performed for a client, surely the TSM client performs a similar query with the TSM server to identify the files required to be restored? Maybe there's a smooth streamlined script for this purpose that IBM just dont want us to have ;) Ah well will keep on looking.. regards, Rowan O'Donoghue Technical Services Manager Unitech Systems Bracken Business Park Bracken Road Sandyford Industrial Estate Dublin 18.

That has been a Holy Grail quest for us customers. There remains no feasible way to get such a list from the product. This condition probably stems from the product philosophy of being file-oriented rather than tape-oriented, in that the customer need not be concerned with the current tapes upon which the files reside. Obviously, DR needs conflict with that neatness, and so we all would like to see the product accommodate such needs. Richard Sims, BU
